Answer 1

Answer:

20 m

Step-by-step explanation:

shadow of the tower = 18 m

shadow of the building = 12 m

height of the building =  ? Y

                            30/Y = 18/12

                             30/Y = 3/2

                                   Y = 30 x 2/3

                                   Y  = 20
